To all whmn it may concern:

Be it known that I, ORLA CALMER PIXLEY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Building Construction, of which the following is a specification.

' In laying up a wall of hollow buildingblocks difficulty is experienced in forming a water-tight joint between the ends of adjacent blocks owing to the small area upon which mortar can be spread and the liability of the mortar to be forced out of place when the blocks are pushed together. It is the obj ect of this invention to obviate the difiiculty mentioned.

The means herein shown for attaining the object of my invention comprises a device intended to be applied to each end of each block before the application of mortar, the devices between adjacent blocks being adapted to catch and retain in contact with the joint the mortar that is forced into the spaces within the blocks when the blocks are pushed into osition.

- Figure 1 of the accompanying drawings is an isometrical perspective view of one form of said retaining device. Fig. 2 is a similar view of the end of a hollow building-block with one of said devices in place thereon. Fig. 3 is a longitudinal sectional view through a hollow building-block and a retaining device in position thereon. Fig. 4 is a view similar to the last preceding view, showing the ends of two hollow buildingblocks joined together according to my invention.

In the drawings, A refers to a hollow building-block, and B to the ducts or spaces there- 1n.

The mortar-retaining device 1 consists of a plate adapted to be applied to the end of a hollow building-block toward the side of the block intended to be the outer face of the wall being laid and having wings 2 ada ted to lie within the ducts of such a block. aid device may be formed-by cutting and punching a sheet into the form shown in the drawings, or it may be formed in any other suitable way. Any material possessing sufficient rigidity may be used in the construction of the device, cardboard and sheet metal being examples of such materials. For clearness of illustration the thickness of the mortar-retaining device 1 is somewhat exaggerthe ends of the blocks and the block to be laid pushed into contact with the end of the block previously laid. This movement forces some of the mortar to the outside of the blocks and some (00) into the ducts B, the wings 2 of the devices 1 preventing the mortar w from falling away from the joint between the blocks. The mortar forced to the outer side of the blocks is now removed in the usual way and the joint is complete. When blocks are to be laid vertically end to end, as in laying a corner, two mortar-retaining devices are laced upon each end of each block on opposite sides of the block.

A joint formed in the manner described is strong and water-tight. The mass of mortar as being held by the wings 2, hardens in place and constitutes a seal for the joint.

I claim as my invention 1. A plate adapted to lie upon the end surface of a building-block and having an angular portion adapted to confine mortar in position close to one of the edges of such block.

2. A plate adapted to lie upon the end surface of a building-block, and having an integral wing adapted to lie within the interior of such block to confine mortar in position close to one of the edges of the block.

3. A device adapted to lie upon the end surface of a hollow building-block and comprising a wing extending at an angle with the body of said device, the outer end of which wing is adapted to lie adjacent to the inner wall of the block.

4. A flat plate adapted'to lie upon the end surface of a hollow building-block, and having a wing punched therefrom, the outer end of which wing is adapted to lie adjacentto the inner wall of the block.
